Definitions

  • Embodiments of the invention herein relate to various structures and ways of making microelectronic packages which can be used in package on package assemblies, and more particularly, to such structures that incorporate wire bonds for as part of the package- on-package connections.
  • Microelectronic devices such as semiconductor chips typically require many input and output connections to other electronic components.
  • the input and output contacts of a semiconductor chip or other comparable device are generally disposed in grid-like patterns that substantially cover a surface of the device (commonly referred to as an "area array") or in elongated rows which may extend parallel to and adjacent each edge of the device's front surface, or in the center of the front surface.
  • areas array a surface of the device
  • devices such as chips must be physically mounted on a substrate such as a printed circuit board, and the contacts of the device must be electrically connected to electrically conductive features of the circuit board.
  • Semiconductor chips are commonly provided in packages that facilitate handling of the chip during manufacture and during mounting of the chip on an external substrate such as a circuit board or other circuit panel.
  • semiconductor chips are provided in packages suitable for surface mounting.
  • Numerous packages of this general type have been proposed for various applications.
  • Most commonly, such packages include a dielectric element, commonly referred to as a "chip carrier" with terminals formed as plated or etched metallic structures on the dielectric. These terminals typically are connected to the contacts of the chip itself by features such as thin traces extending along the chip carrier itself and by fine leads or wires extending between the contacts of the chip and the terminals or traces.
  • the package In a surface mounting operation, the package is placed onto a circuit board so that each terminal on the package is aligned with a corresponding contact pad on the circuit board. Solder or other bonding material is provided between the terminals and the contact pads.
  • the package can be permanently bonded in place by heating the assembly so as to melt or "reflow" the solder or otherwise activate the bonding material.
  • solder masses in the form of solder balls, typically about 0.1 mm and about 0.8 mm (5 and 30 mils) in diameter, attached to the terminals of the package.
  • a package having an array of solder balls projecting from its bottom surface is commonly referred to as a ball grid array or "BGA” package.
  • Other packages, referred to as land grid array or “LGA” packages are secured to the substrate by thin layers or lands formed from solder.
  • Packages of this type can be quite compact.
  • Certain packages, commonly referred to as "chip scale packages” occupy an area of the circuit board equal to, or only slightly larger than, the area of the device incorporated in the package. This is advantageous in that it reduces the overall size of the assembly and permits the use of short interconnections between various devices on the substrate, which in turn limits signal propagation time between devices and thus facilitates operation of the assembly at high speeds.
  • Packaged semiconductor chips are often provided in "stacked" arrangements, wherein one package is provided, for example, on a circuit board, and another package is mounted on top of the first package. These arrangements can allow a number of different chips to be mounted within a single footprint on a circuit board and can further facilitate high-speed operation by providing a short interconnection between packages. Often, this interconnect distance is only slightly larger than the thickness of the chip itself. For interconnection to be achieved within a stack of chip packages, it is necessary to provide structures for mechanical and electrical connection on both sides of each package (except for the topmost package). This has been done, for example, by providing contact pads or lands on both sides of the substrate to which the chip is mounted, the pads being connected through the substrate by conductive vias or the like.
  • solder balls or the like have been used to bridge the gap between the contacts on the top of a lower substrate to the contacts on the bottom of the next higher substrate.
  • the solder balls must be higher than the height of the chip in order to connect the contacts. Examples of stacked chip arrangements and interconnect structures are provided in U.S. Patent App. Pub. No. 2010/0232129 ("the ⁇ 29 Publication"), the disclosure of which is incorporated by reference herein in its entirety.
  • Microcontact elements in the form of elongated posts or pins may be used to connect microelectronic packages to circuit boards and for other connections in microelectronic packaging.
  • microcontacts have been formed by etching a metallic structure including one or more metallic layers to form the microcontacts. The etching process limits the size of the microcontacts.
  • Conventional etching processes typically cannot form microcontacts with a large ratio of height to maximum width, referred to herein as "aspect ratio”. It has been difficult or impossible to form arrays of microcontacts with appreciable height and very small pitch or spacing between adjacent microcontacts.
  • the configurations of the microcontacts formed by conventional etching processes are limited. Despite all of the above-described advances in the art, still further improvements in making and testing microelectronic packages would be desirable.
  • a component can include a generally planar element having oppositely-facing first and second surfaces extending in first and second transverse directions, a reinforcing dielectric layer overlying the first surface of the generally planar element, an encapsulation overlying the reinforcing dielectric layer, and a plurality of wire bonds.
  • the generally planar element can have a plurality of contacts at the first surface.
  • the encapsulation can have a major surface facing away from the first surface of the generally planar element.
  • Each wire bond can have a base joined with a contact of the plurality of contacts, and a tip remote from the base at the major surface of the encapsulation.
  • the wire bonds can have first portions extending within at least a portion of the reinforcing dielectric layer and second portions extending within the encapsulation.
  • the first portions of at least some of the wire bonds can have bends that change an extension direction of the respective wire bond in at least one of the first and second directions.
  • the reinforcing dielectric layer can have protruding regions surrounding respective wire bonds of the plurality of wire bonds, the protruding regions extending to greater peak heights from the first surface of the generally planar element than portions of the reinforcing dielectric layer between adjacent ones of the protruding regions.
  • the peak heights of the protruding regions can coincide with points of contact between the reinforcing dielectric layer and individual ones of the wire bonds.
  • the component can comprise microelectronic package.
  • the microelectronic package can also include a microelectronic element having oppositely-facing top and bottom surfaces.
  • the bottom surface can face the first surface of the generally planar element and can be mechanically coupled therewith.
  • the major surface of the encapsulation can overlie the top surface of the microelectronic element.
  • the tips of a subset of the at least some of the wire bonds overlie the top surface of the microelectronic element.
  • the bases of the wire bonds can define a first minimum pitch between adjacent ones of the bases, and the tips of the wire bonds can define a second minimum pitch between adjacent ones of the tips, the second minimum pitch being greater than the first minimum pitch.
  • the dielectric layer can overlie the top surface of the microelectronic element.
  • the reinforcing dielectric layer can include a first reinforcing dielectric layer overlying the first surface of the generally planar element, and a second reinforcing dielectric layer overlying the first reinforcing dielectric layer and defining an upper surface of the reinforcing dielectric layer.
  • the bends of the first portions of the wire bonds can be first bends, and the at least some of the wire bonds can each include a second bend changing the extension direction of the respective wire bond in at least one of the first and second directions.
  • at least some of the second bends of the wire bonds can be disposed within the reinforcing dielectric layer.
  • the reinforcing dielectric layer can be configured to maintain the position of the tips of the wire bonds in a third direction perpendicular to the first and second directions when a force is applied to the tips of the wire bonds in the third direction.
  • the microelectronic package described above can also include a plurality of upper terminals joined with corresponding ones of the wire bonds.
  • the upper terminals can be at the major surface of the encapsulation and can be configured to be electrically connected with conductive elements of a component external to the microelectronic package.
